House extensions in Kensington often require a more considered approach due to conservation areas, period properties, and the planning expectations of the Royal Borough of Kensington and Chelsea. Many homes are subject to stricter controls on scale, materials, and massing, making early feasibility and design coordination essential.
Whether extending a Victorian terrace, a lateral apartment, or a mews property, we focus on proportion, neighbour impact, and buildability from the outset. This approach helps avoid delays, reduces planning risk, and ensures the finished extension integrates naturally with its surroundings.
Homes in Kensington are prized for their character and setting, but many were never designed for modern living. Rather than compromising on space or uprooting entirely, a well-planned extension allows you to adapt your home intelligently — improving how it functions while respecting what makes it special.
A carefully designed house extension in Kensington can:
Transform everyday living by opening up kitchens, dining areas, and family spaces
Create purpose-built rooms such as home offices, guest suites, or discreet utility areas
Add long-term value in one of London’s most tightly held residential markets
Future-proof your home, allowing it to evolve with changing family needs
When done properly, an extension shouldn’t feel like an addition. It should feel like a natural continuation of the original house — enhancing space, light, and usability without diluting its architectural integrity.
Rear Extensions
Perfect for opening up kitchen and dining spaces, bringing in natural light and garden views.
Side Return Extensions
Utilise narrow alleyways to expand living areas without compromising outdoor space.
Wrap-Around Extensions
Combine rear and side extensions for maximum impact, ideal for open-plan living.
Double-Storey Extensions
Add bedrooms or bathrooms upstairs while enhancing ground-floor space.
Over-Structure Extensions
In Kensington, rear and side return extensions are particularly popular due to narrow plots and limited outdoor space. Wrap-around and double-storey extensions can also be viable, but often require careful planning justification and detailed neighbour engagement.
Our role is to advise early on what is achievable, helping clients invest in solutions that suit both the property and the local planning context.
We’ve developed a streamlined process to make your extension project smooth and stress-free. Here’s what you can expect:
We swiftly respond to your building requirements upon your contact, gathering essential information such as your project vision, timelines, and specific needs. This initial step is crucial as it helps tailor our approach to address your unique building needs from the outset.
We offer a detailed consultation—whether in person or by phone—to discuss design, budget, and challenges. Our experts then assess the site and provide a transparent estimate, ensuring clear communication and a strong partnership.
Once the contract is signed, we promptly begin the project, arriving fully prepared to bring your vision to life. With an online monitoring portal and biweekly meetings, we keep you updated, address any concerns, and ensure everything stays on track.
Upon project completion, we conduct a final walkthrough with you to ensure every detail meets your standards, followed by providing comprehensive aftercare instructions and support for any post-completion needs. Our commitment extends beyond the build, ensuring that you are delighted and well-supported even after the project is finished.
